Both those colors are more in the medium range in the color spectrum.
Since you said lighter and that you hate the amber color which one would assume you are looking at a warm tone with a hint of red. My suggestion is to check out nutmeg from duraseal. Now it doesnt have to be duraseal but thats what i work with so thats what i can speak about with confidence. I believe nutmeg is a "stock" color most brands carry.

If looking for somthing darker. Chestnut is a happy medium between nutmeg and medium brown.

If your floor guy is any good he should just show you any color you want right ON your floor.

Looking at a sample board or little swatches can be decieving because onecolor on a new floor will have a different look and feel on a floor thats 50 yrds old
